Methods that enhance homeland security and disaster emergency operations through biometrics and Radio Frequency Identification (RFID) were studied. Biometrics can be used in visas and e-passports for border security, identity verification at airports, access control and safety for personnel in basic military training, and security for facilities in troops. RFID technology speeds the movement of people crossing borders, tracks baggage and polices airport access, provides better management of wounded soldiers and supply chains in military, detects unauthorised shipments for marine security, and improves disaster tracking, response and relief operations. Challenges and future work concerning biometrics and RFID in homeland security were also discussed. Copyright © 2012 Inderscience Enterprises Ltd.

Biometrics has been used in healthcare systems, banking and finance, energy systems, access control in computer centres, military, and homeland security such as e-passport, border crossing control, airport security, criminal identification, and fighting terrorists. Biometric technologies such as face, fingerprint and iris recognition, multi-biometrics, and their technology intelligence, applications, and advances were studied. 13 attributes of six biometric technologies including face, fingerprint, iris, voice, hand geometry and signature recognition, and false reject rates (FRR) and false accept rates (FAR) of the six biometric technologies were summarised and compared based on technology evaluation or scenario evaluation. Challenges and future research of biometrics were also discussed. Copyright © 2011 Inderscience Enterprises Ltd.

In this manuscript, we provide a framework for zero-Hopf singularity for general delayed differential equations (DDEs). We formulate the explicit conditions such that zero-Hopf singularity occurs for general DDEs and derive the corresponding normal forms up to the third-order terms. As an application of our framework, we discuss zero-Hopf singularity for a Fitzhugh-Nagumo model with delayed feedback control. © 2013 Springer Science+Business Media Dordrecht.

The maximum read range of a Radio Frequency Identification (RFID) system depends on a number of factors. In this paper, the maximum read ranges of an RFID system with a handheld RFID reader and another RFID system with a fixed RFID reader were tested when a tag was attached to different materials. Distinguishing factors that influence the maximum read range is important. A design of experiments (DOE) method was used to understand and quantify the relative influence of three factors (the antenna number, the tagged material, and the RF interference) on the maximum read range of the RFID system with a fixed RFID reader. The influences of the three factors and their interaction effects were classified by an order of importance. The methods in this paper also apply to the study of other RFID systems and determining the relative influences of other selected factors or parameters as well as other materials.

Radio Frequency Identification (RFID) can improve services and management in medical and healthcare systems. It helps monitor patients, link patients with key drugs and personnel, and track medical devices and potentially hazardous materials in hospitals. In telemedicine, RFID integrated with sensors can monitor blood products' temperature, send patients' physiological status, and identify patients' locations in case of emergency. Based on the EPCglobal Network, RFID can track all transactions from the beginning to the end in the pharmaceutical industry, which combats counterfeit products and protects product brands. Information security about RFID tags, challenges, and future work are also discussed. Copyright © 2010 Inderscience Enterprises Ltd.
